Do you mean infrasonically? And by this do you mean they are damped?

Yes.
Why? In this way the system is free from vibrations of any kind, in particular in the audio band.
That is what puts yourself in a situation of minimum error. Systematic errors, more precisely.

I think you are funny. You would argue on subject on which you don't have any practical idea and any experience. So have fun! I think I have written too much....
Anyway your reactions are not new to me..... same old story!

Yes, infrasonic.
No. Damping is minimal. In theory damping is not desirable in order to have an infinite Q at resonance so that all the energy is dissipated at such frequency (or lower, i.e. is a mechanical low pass filter). In practice you have minimal damping.
Damping means just that you dissipate the energy regardless of the frequency or in wide band if you like. Here the target is making a system that has got only subsonic vibration modes. The difference is that when you just damp some part of that energy will influence the spectral balance of your interest. Using the infrasonic suspension you just don't make it happen.
The best way is the air spring that achieves the lowest possible frequency.
Moss has been producing air springs for audio equipment for many years. They can be used with any component from the source to the speakers and come in different sizes.

And you have? At which stage in pulling your credit card from your wallet did the practical ideas and experience become magically imparted to you?

Hmmm... so others have expressed disdain after reading your nonsense...? Surprising.

"subsonically coupled"? To what? Earth? Cosmos? Why? What for?

What he means to say is that they are decoupled from each other. I.e. there is a suspension system between the various drivers. And the resonance frequency is very low (as it should be). I.e. somewhere below 20Hz? Hence the term subsonic..... I suppose.

[Cal Weldon]

Hence my question concerning how they are damped as I didn't figure he was talking about simply bolting them together.

Cheers.

For free!

Yes, I would be surprised of the contrary instead. If you think it's nonsense why are you so interested in reading and posting?

Schadenfreude? There is a certain pleasure in watching deluded people flail around with meaningless terms and phrases to try and assert their opinion as fact.

Seriously... it angers me slightly that you feel you can post pseudo science about why your 'sound field' is so superior to anything anyone else has heard and expect people to believe it, even belittling people for not... thats the point of this thread. You are a prime example of the type of poster that inspired this thread "What happened to diyaudio?".

Anyway... wasted keystrokes...

If you want. But I think I have written a lot so that you can make some experience for free. If you try to understand how it works!
I mean the technical points: vibrations, coupling, decoupling, rigid system, effective bessel alignment, controlling the the back wave, the influence of the room etc.....

Instead it looks like you have nothing to tell except your opinion on what you don't know and understand. Augh!
